From folding cars to robotic walls: 5 innovations to make future cities far more livable

Big cities across the globe will soon be getting much, much bigger. As architect Kent Larson shares in this future-focused talk from TEDxBoston, 90 percent of the world’s population growth is expected to happen in cities. But while newly established cities tend to sprawl to accommodate growth, Larson envisions that the metropolises of the future will look more like cities of the past — for example, Paris — with tight-knit neighborhoods offering residents everything they need within the radius of a 20-minute walk.

So how will we live comfortably with even more people crammed into even smaller areas?
